概括

在平衡障碍期间的大脑反应,如平衡N1和theta活动,不需要积极的姿势控制. 这些神经信号可能表明大脑是大脑.

科学领域:

神经科学是一个神经科学.
生物力学生物力学
人类运动控制人体运动控制

背景情况:

常态平衡涉及复杂的神经处理,包括快速的反射和更长时间的皮质活动.
脑电图 (EEG) 研究确定平衡N1和中额头的太功率是姿势障碍期间皮质活动的标志物.
这些皮质标记物在积极的姿势控制与一般感官事件检测中的确切作用仍然不清楚.

研究的目的:

为了确定平衡N1和中额头答案是否依赖于积极的姿势控制或反映一般的感官处理.
为了将平衡扰乱的神经处理与纠正行动的运动执行分开.

主要方法:

参与者在机器人平衡模拟器中经历了相同的支表面扰动.
在主动平衡和被动运动条件下测量皮层 (EEG) 和肌肉活动.
系统地操纵感官反 (全身与仅脚板) 和运动参与 (同位数收缩与放松).

主要成果:

在平衡N1和中额头答应持续,在被动运动中仅有适度的幅度减少,尽管肌肉活动显著减少.
皮层反应即使在放松的姿势中仍然存在,肌肉参与最小,感官反发生变化.
在被动和放松的条件下,肌肉反应明显被抑制,而皮质标记物显示持久性.

结论:

平衡N1和中额头西塔不依赖于积极的姿势控制.
这些皮质标记指数早期检测和评估意想不到的感官事件,而不是产生纠正行动.
研究结果表明,在姿势障碍期间,在预测错误或惊喜处理中起作用.

关键词:

Indirect Motor Pathways

Indirect Motor Pathways

The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

Major Somatic Sensory Pathways

Major Somatic Sensory Pathways

Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Equilibrium and Balance

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

The Vestibular System

The Vestibular System

The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Somatic Spinal Reflexes

Somatic Spinal Reflexes

Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

Functional Brain Systems: Reticular Formation

Functional Brain Systems: Reticular Formation

The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...
